The CLL is focused on constraining Quaternary environmental change in a range of environmental settings. Specific research objectives are focused on coastal settings,geoarchaeological applications, extending the age range of luminescence dating using radiofluorescence, exploration of luminescence-thermochronometry, constraining complex environmental dosimetry and the application of ESR dating. As such the group is involved in a range of different research projects including the “Our Way to Europe” SFB806 consortium grant and the RLum.Network. Further information about luminescence dating and ESR dating, current and completed research grants can be found here:
- A new Collaborative Research Centre (CRC) led by Prof. Tibor Dunai from the Institute of Geology and Mineralogy at the University of Cologne titled “Earth-Evolution at the Dry Limit” was funded by the DfG in August 2016. This CRC seeks to explore the mutual evolutionary relationships between Earth surface processes and biota, through focussing on the Atacama desert. The CLL has been awarded c. 360k € to contribute to the CRC both by providing chronologies to the different sub-projects, and also through developing new techniques capable of extending the age range of luminescence dating. Specifically the CLL has been awarded funds to purchase a new Risø luminescence reader capable of measuring violet stimulated luminescence, which other researchers have shown may enable timescales in excess of 1 Myr to be dated (e.g. Ankjaegaard et al., 2015). Georgina King and Helmut Brückner are PIs of the project and Dominik Brill is post-doctoral researcher.
- Dr Christoph Gruetzner, Research Assistant at Cambridge University and specialist for earthquake geology, geophysics and paleoseismology, was interviewed by Spiegel Online on the topic of holocene surface ruptures of the Rurrand Fault (Germany). The OSL dating was performed by Dr Daniela Hülle. Read the interview here.
- A new research project titled OSL surface exposure dating of wave-emplaced boulders - Improving the use of coarse-clast records for coastal hazard assessments was granted to Dominik Brill and Simon Matthias May by the German Research Council (DFG) (c. 31,000 €, duration of three years). The research project addresses the necessity of innovative approaches to date the transport of coastal boulders by testing the recently developed optically stimulated luminescence (OSL) surface exposure dating technique. OSL surface exposure dating will be applied to coastal boulders at Cabo de Trafalgar (Cádiz, Spain), some of which have been linked with the 1755 Lisbon tsunami.
- Members of the CLL were recently involved in an outreach event at the Neanderthal Museum. Daniela Hülle created a pecha kucha explaining luminescence dating which you can watch here
